Ubuntu 10.04通过UUID来区分各个磁盘分区，在/etc/fstab配置文件中就是通过UUID来挂载分区的。
UUID，英文全称为：Universally Unique Identifier。
下面介绍2种查看分区UUID的方法：
1.在终端中执行命令：
blkid
返回结果：
/dev/sda1: UUID="E414E02914E00082" TYPE="ntfs"
/dev/sda5: UUID="E4DCB02EDCAFF8C6" TYPE="ntfs"
/dev/sda6: LABEL="e-disk" UUID="d8463d0b-41f6-4f9b-acc1-a481dfa9a9c5" TYPE="ext4"
/dev/sda7: UUID="CA8A22CE8A22B6BB" TYPE="ntfs"
/dev/sda8: UUID="0C38BF5538BF3C90" TYPE="ntfs"
/dev/sda9: UUID="dd85f22a-4130-4ca9-bdc4-2bfbf0a76801" TYPE="swap"
/dev/sda10: UUID="2ea3fd65-23ef-4930-a87c-1788f6bc3f4d" TYPE="ext4"
/dev/sdb: UUID="BC90-1EEA" TYPE="vfat"
2.在终端中执行命令：
ls -l /dev/disk/by-uuid/
返回结果：
